我有一小段代码(一个较大程序的一部分)只检查驱动器号和 CDROM 的状态
import wmi
print '--checkCDContent--'
c=wmi.WMI()
cdrom = c.Win32_CDROMDrive()
status = cdrom[0].MediaLoaded
drive = cdrom[0].Drive
print drive, status
作为较大程序的一部分,我必须使用 cxFreeze 编译代码以创建 exe。为了测试我的问题,我单独使用上面的代码来复制它。
当我从硬盘驱动器运行 .exe 时,它运行正常。当我从 CD 本身(我的最终目标)运行它时,我收到以下错误
X:\>CDrun.exe
--checkCDContent--
Traceback (most recent call last):

我怀疑它出现了这个错误,因为代码实际上是从 CD 运行的,同时它试图获取 CD 的状态更新。任何人都可以验证这一点并提出解决方案吗?
